QLineedit is a one line of plain text which you may not easily handle such character formatting. On the other hand Qt provides text widgets for plain and rich text, that can accept formatting such as html. For instance the QTextEdit widget can be used and render such formatting of text with html tags.

QString html = "01<b>23456789</b>";
QTextEdit::setHtml(html);
